MACHINE FOR INSERTING PROTECTORS, SLUGS, OR FASTENINGS.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed October 3, 1904. Serial No. 227,014.

GAN, a citizen of the United States, residing at Lawrence, in the countyof Essex and Commonwealth of Massachusetts, have invented certainImprovements in Machines for Inserting Protectors, Slugs, or Fastenings,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines forinserting protectors, slugs,fastenings or like devices into stock, more particularly to the feedingmechanism and work-support used in conjunction with such machines.

As machines embodying the features of this invention can be utilizedwith equal efficiency when any of the above-mentioned de vices are beinginserted, the term protector will hereinafter be used generically todesignate any device of the nature set forth, and wherever the wordprotector occurs herein it should be held to include any one or alldevices of the character above specified, as the context may admit orrequire.

One object of the invention is to provide improved means for presentingstock to the inserting mechanism, said means being universally movablein a single plane and acting in conjunction with suitable guides so thatprotectors may be inserted in various designs over any portion of thestock being operated upon.

Another object of the invention is to provide means for correctlypositioning the stock at the beginning of the feed movement, which meansis controlled by the device utilized for rendering the stock-feedingmeans inoperative after a particular design or part of a design has beencompleted.

Another object of the invention is to provide improved stock-sustainingmeans used in combination with the positioning means above mentioned,whereby different rows of protectors, the first protector of each ofwhich is in a different relation to the extreme end of the stock, may beinserted symmetrically.

Another object of the invention is to provide stock-presenting meanswhich operates uniformly and'which. will not be afiected in itsoperation by the vibration caused when the driver is actuated forinserting a protector into the stock.

As herein shown the stock is preferably sustained by a carriage, movablein two directions in a horizontal plane, and also movable vertically bymeans under control of the operator, as a lever fulcrumed on astationary part of the machine.

This lever is so connected to the remaining portions of the mechanismthat it controls the operation of the stock-feeding means, and themovement of a novel stop for positioning the stock at the beginning ofthe feed movement, said stop being normally held depressed and "out ofengagement with the stock-sustaining ajustable stops for limiting itsmovement.

The machine herein shown and described is adapted to insert a protectorhaving laterally-extending wings, and also insert simultaneously a sluginto the stock inclosed by the wings of the protector, but my improvedstock-presenting means is not limited to use with such type of machineand may be used with any protector inserting machine.

' In the accompanying drawings 'which illustrate the preferredembodiment of the invention, Figure 1 is an elevation showing theleft-hand side of a machine for inserting ;a protector and a slugsimultaneously; Fig. '2 is a detail view, partly in section, showing inside elevation the yieldingly sustained table, the carriage movablymounted thereon, and the mechanism for feeding the carriage; Fig. 3 is adetail, partly in section, taken on the line 00-09 of Fig. 2; Fig. 4 isa partial sectional view taken on the line yg of Fig. 3; Fig. 5 is aplan view of the stock-carrylng plate, the carriage and its feedingmechanism, and shows, in inoperative position, the guiding mechanism forcausing the stock-carrying plate to move transversely of the carriage;Fig. 6 is a plan View similar to Fig. 5, showing, in full lines, one ofthe gage plates of the guiding mechanism in operative position for oneadjustmerit, and, in dotted lines, in position for a differentadjustment; Fig. 7 is a detail view showing the rear side of thepawl-control- -ent position; and Fig. 10 is a plan view of a tap-soleshowing protectors and fastenings inserted in one form of design.

Referring to Fig. l of the drawings, 2 designates a standard on which ismounted a head 4 that carries the main shaft 6. A

hopper 8 in which protectors are contained is supported by a bracket 10projecting from the head, and a reel 14 which carries wire for formingfastenings or slugs is supported by a bracket 12. The protectors travelfrom the hopper down a raceway 16 which is provided with an arrester anda let-off that release the protectors singly, an ejector 15 pushing theprotectors from the end of the raceway into .an opening in a transferrer18. After a protector has been placed in said opening the transferrer ismoved laterally to place the protector carried thereby in alinement withthe driver, which drives the protector through an opening in afoot-plate 19 into the stock. The protector-driver is provided with alongitudinal passage and is carried by a protector-driver bar 27 alsoprovided with a longitudinal passage, the longitudinal passage in theprotector-driver bar being intersected by a recess which receives afastening-carrier movable with the bar. The fastening-carrier isprovided with an opening into which the end of the wire or fasteningmaterial is fed, and thereafter said carrier is moved into the recess inthe driver bar, the movement of the carrier severing the wire to form afastening and also placlng the fastening in alinement with thefastening-driven The fastening driver moves in the longitudinal passageof the protector-driver and is carried by a driver bar 26 movable in thelongitudinal passage of the protector-driver bar, whereby thefastening-driver is adapted to drive a fastening through thelongitudinal passage of the protector-driver into the stock inclosed bythe wings of the protector. The protectordriver bar is positivelyactuated by a lever 22 which is connected by an adjustable link 30 tothe fastening-driver bar lever 28, as shown in Fig. 1, and whenever thelever 22 is moved the lever 28 also will be moved, so that a protectorand a fastening will be driven simultaneously.

Pivoted to the head 4 is a lever 32 which carries a roller adapted totravel in the cam groove 33 of a cam block 31 mounted on the 7 mainshaft, the other end of the leverhaving herein more fully described, asit forms no part of the present invention.

In the preferred form of my invention as herein shown, astock-supporting plate 20 is mounted on a carriage 82 which is movablymounted on a table 66 having a hollow shank 64 that loosely surroundsthe upper end of a stock-supporting spindle 60. The shank movesvertically on the spindle and is prevented from rotating by a screw 68carried by said shank and projecting into a vertical slot 70 in thespindle, as shown in Fig. 2, and fastened to said spindle is a weight 62which takes up the impact of the drivers and helps to prevent thespindle from yielding when a protector and fastening are being driveninto the stock supported by the plate 20. In one side of the weight isformed a guideway 73 which is entered by a short guide rod 71 projectingdownwardly from the shank 64 to aid the screw 68 in preventing the tablefrom rotating relatively to the spindle. r

A coiled spring 72 is confined within the hollow shank 64 between theupper end of the spindle 60 and the lower surface of the table 66 andkeeps the'table normally in an elevated position, so' as to' hold thestock yieldingly against'the lower surface of the footplate. Fordepressing the table against the stress of spring 7 2 when it is desiredto release the stock or to remove the stockcarrying plate from thecarriage, a lever 74 is provided which is pivoted at 76 in a slot in theupper end of the spindle, said lever projecting outwardly through a slot7 8 in the hollow shank of'the table, as shown in Fig. 3. By pressingdownwardly on the lever 74 its lower edge will engage the lower edge ofthe slot in the hollow shank and depress the table.

As shown in Figs. 2 and 3, the table is provided with guideways 80 onwhich the carriage 82 is adapted to travel, the carriage being providedon each side with rackteeth 84 that mesh with pinions 86, 86 fastened toa stud shaft 88 mounted in the table. Rigidly connected with one of thepinions is a ratchet wheel 90 which'is engaged by feeding pawls 92carried by an oscillating pawl-carrier 94 pivotally mount ed on the studshaft 88 and connected at 95 to one end of a rod 44, as shown .inFig. 1. The other end of the rod 44' is fastened to an elbow lever 42pivoted to the standard 2 and connected by means of the rod 40 withlever 32, so that whenever the lever 32 is elevated for depressing thespindle, the pawl-carrier will be moved forwardly in the direction ofthe arrow, Fig. 2, and the pawls carried thereby will engage and turnthe ratchet wheel 90, so as to feed the carriage 82 toward the rear ofthe machine, the carriage being prevented from overthrowing, or movingtoo freely, by a friction plunger 85 mounted in the table and bearingagainst the underneathside of the carriage. A reverse movement of thelever 32 moves the pawl-carrier rearwardly to carry the pawls back overthe ratchet wheel into position for engaging the ratchet wheelpreparatory to turning it when the pawl-carrier is again movedforwardly.

A pawl-controlling plate 96 is pivotally mounted on the stud shaft 88and is held in adjusted position by a screw 98 which projects through aslot 100 in said plate and clamps it to one side of the table, saidplate being provided with a pawl knock-out 102 which is engaged duringthe rearward movement of the pawl-carrier by a pin 104, carried by theawls, whereby said pawls are disengaged f fom the ratchet wheel. Whenthe plate 96 is in the position shown in Fig. 9 the pawls will bedisengaged from the ratchet wheel before the pawl-carrier has completedits rearward movement. Consequently when the pawl-carrier is movedforwardly the pawls will not ree'ngage said ratchet wheel until thepawl-carrier has moved forward quite a distance, so that but a slightmovement will be imparted to the pinions 86, 86, and the carriage willbe fed only a short distance. When the plate 96 is in the position shownin Fig. 2 the pawls will not be disengaged from the ratchet wheel untilthe pawl-carrier has nearly completed its rearward movement, see Fig. 8,so that in the forward movement of the pawlcarrier the pawls willreengage the ratchet wheel approximately at the beginning of saidmovement and will feed the carriage the full distance. As the plate 96can be adjusted in any desired posltion, the distance the carriage is tobe fed at each forward movement of the pawl-carrier may be accuratelydetermined, and for obtaining a very fine and accurate feed withoutusing a fine-toothed ratchet wheel the pawls are of different lengthsand movable relatively to each other. i

As the machine is arranged to stop with the work support depressed, thelever 32 will stop in its elevated posit-ion and the pawlcarrier willstop at the end of its forward movement, in the position shown in Figs.1 and 2, the pawls being then in engagement with the ratchet wheel.Therefore it is necessary to first disengage the pawls from the ratchetwheel before'the' carriage can be moved on the table, and this isprovided for by the followingmechanism: A dog 12 1 is pivoted to theside of the table and has a forwardly-projecting end that stands overthepin lOt when the pawl-carrier is at the end of its forward movement, aspring 126 being fastened to the'other end of the dog to hold theforwardly projecting end thereof normally in an elevated position. Thedog is connected by a link 122 to the lever 74, so that by moving saidlever downwardly the end of the dog will engage the pin 104 and removethe pawls from engagement with the teeth of the ratchet wheel, as shownin Fig. 7, and at such times the carriage may be moved freely back andforth on the table.

Projecting from one side of the sleeve 64: is a bracket 106 to which alever 108 is pivoted at 110, as shown in Figs. 3 and 4, one end of saidlever having fastened thereto a headed screw 112 which projects throughan elongated slot in the lever 74, so that whenever the lever 74 ismoved downwardly the lever 108 will be rocked on its pivot to elevate apin 116. The pin 116, when in its elevated position, is adapted to actas a stop for positioning the stock-carrying plate relatively to thedrivers when said plate is moved into starting position, said pin beingvertically movable in a guideway formed in the table and being heldnormally depressed out of the path of the carriage 82 by a coiled spring118 which, at one end, bears against a head on the pin and at its otherend against the bottom of the table. The upper end of the pin isprovided with a spring-pressed plunger, see Fig. 3, so that when thecarriage is in its rearward position, and at such times covering the endof the pin, a downward movement of the lever 74:, andconsequently anupward movement of the pin 116, will cause the spring-pressed plunger toyield against the lower surface of the carriage. If the pin were notprovided with a yielding plunger the engagement of the end of the pinwith the lower surface of the carriage would limit the downward movementof the lever 74 when the carriage was in its. rearward position.

From the foregoing description it will be seen that a downward movementof lever 74 lowers the table to release the stock from engagement withthe foot-plate andto enablethe stock-carrying plate to be removed fromthe carriage; removes the pawls from engagement with the ratchet wheel,so that the carriage may be moved back to starting position or to anydesired position on the table; and elevates the pin 116 into'operative:position to be engaged by the end of the stock-carrying plate when itis moved into starting position, for it will be understood that as soonas the carriage has been moved toward the front of the machine thespringpressed plunger in the end of the pin will be released and willrise upwardly.

The stock-carrying plate 20 is shown in Fig. 5 and comprises a platewhich is substantially the shape of the forepart of a sole, one end ofthe plate having a projection 31 and two notches 27 and 29, and theother end of the plate having a handle 21 by which the operator movesthe plate and carriage transversely thereof for a purpose hereinafterdescribed.

F or producing the design shown in Fig. 10 the operator first adjuststhe plate 96,

which carries the pawl knockout 102, so as to determine the length ofeach feeding movement of the carriage, as this represents the distancebetween two protectors and the carriage and pawl-carrier being in theposition shown in Fig. 1, the lever 74 is depressed to lower the tableand disengage the pawls from the ratchet wheel and also'to elevate thepin 116. The plate 20, having a sole or tap-sole attached thereto, isthen placed on the carriage with the tongue on the plate resting in thegroove in the upper surface of the carriage, and the carriage is movedrearwardly on the table until the projection 40- 31 on the end of theplate engages the plunger'inv the end of the pin 116, see Fig. 5. Thestock is now in position to receive the first protector and fastening ofthe center row a, and the lever 74 is released so that the table canmove upwardly to clamp the stock yieldingly against the foot-plate. Atthe same time the pin 116 will be lowered out of the path of movement ofthe carriage and the pawls will reengage the ratchet wheel. The machineis now started, and at the first downward movement of the lever 32 forelevating the spindle to receive the pawls will engage and rotate theratchet wheel, and as the ratchet wheel is rigidly fastened to one ofthe pinions 86 in engagement with the rack-teeth of the carriage, the

carriage and plate 20 will be moved toward the rear of the machine toplace the stock in position to receive the next protector and fasteningof the center row, the carriage and stock-carrying plate being movedrearwardly the distance between two protectors at each cycle ofoperations of the machine.

When the last protector and fastening of the center row have beeninserted the operator stops the machine, the carriage and pawl-carrierbeing then in the position shown in Fig. 2, and the lever 74 is againdegressed to lower the table and to remove the pawls from engagementwith the ratchet wheel.

The carriage and stock-carrying plate .are then moved toward the frontof the machine and the spring-pressed plunger in the end of pin 116 willmove upwardly when released by the carriage, so as to be in position tobe engaged by the end of the plate 20 when it is again moved intostarting position.

For guiding the stock-carrying plate while protectors are being insertedin the outer rows 12 and b, and also the rows 0 and 0, a guidingmechanism is provided which comprises a bar 130 having projectingupwardly therefrom arms 132 and 133 which carry at their ends adjustablegage plates 134 and 135, as shown in Figs. 3, 5 and 6. Said bar 130slides in a guideway formed in the table,

and is provided with a downwardly-projecting pin 136 which enters a slot138 in a shifting lever 140, that is pivoted at 142 to the table, themovement of said lever for one adjustment of the guiding mechanism beinglimited by a part 144 which engages adjust" the lever by means of aspring 160 which, at.

one end, engages a pin projecting from the lever, and at its other'endengages a-pin projecting from the handle. By moving the handle 150outwardly on the lever against the tension of said spring 160 and thenmoving the lever to the left until the part 144 engages the contactscrew 146, the gage plate 135 will be brought into the position shown infull lines in Fig. 6. The carriage and plate are then moved intostarting position, and during said movement the plate 135 will engagethe edge of the sole carried by the plate 20 and will move said platetransversely of the carriage, so that the notch 29 in the end of theplate will engage the plunger in the end of the pin 116. The stock willnow be in position for receiving the first protector and fastening ofthe row I), as shown in full lines in Fig. 6, and as the carriage ismoved toward the rear of the machine the gage plate bearing against theedge of the sole will cause the stock-carrying plate I kind herein shownonly one stock-carrying 20 to be moved transversely of the carriage inthe direction of the arrow in said figure, so that the protectors willbe inserted in a line conforming to the contour of the sole. Thetransverse movement of the stock-carrying plate in this directioncontinues until the widest part of the sole has passed the gage plate,and thereafter it is necessary for the operator to move thestock-carrying plate in the opposite direction and hold the edge of thesole against the gage plate, so that the remainder of the protectors andfastenings of this row will also be inserted in a line conforming to thecontour of the sole. These operations are repeated for inserting the row6, except that the lever140 is shifted in the opposite direction formoving the gage plate 134 into operative position, the movement of thelever being limited by part 1 14 and contact screw 145. For insertingthe rows 0 and 0 it is necessary to move the gage plates farther awayfrom the center of the machine than when inserting rows 3) and b, and toprovide for this the handle 150 is allowed to move to its innermostposition, the contact screws 152 and 153 cooperating with the stop 15 1for limiting the movement of the lever as shown in dotted lines in Fig.6. The same operations are repeated for inserting rows 0 and c as wereperformed when the protectors of rows 6 and b were inserted, the onlydifierence between these rows being that the first protectors of rows 0and 0' are farther from the toe-end of the sole than the firstprotectors of rows Z) and b, as shown in Fig. 10, this being effected bymoving the stock-carrying plate farther rearwardly and not using the pin116 when positioning the stock for the first protectors of rows 0 and c.

Fig. 10 shows one form of design in which protectors and fastenings maybe inserted, but various other designs may be formed, for instance,instead of inserting four rows conforming to the contour of the sole,two rows only may be inserted, and three straight rows, or the guidingmechanism may be dispensed with and five straight rows inserted.

By adjusting the contact screws in the guiding mechanism the distancebetween the rows of protectors may be varied. It is possible with myimproved mechanism to insert protectors, slugs, or fastenings in variousdesigns by simply changing the adjustment of the guiding mechanism, andthe distance between the protectors may be varied by changing theposition of the pawl-controlling plate 96. By manually moving thestock-carrying plate back and forth transversely of the carriage as thecarriage is being fed rearwardly it is possible to insert protectors ina design forming the letter S or various other designs, depending on theskill of the operator.

In a stock-presenting mechanism of the I plate or pattern plate is used,although protectors may be inserted in various designs, whereaspreviously it has been the practice to use a difierent stock-carryingplate for every different design. The feeding mechanism does not actdirectly on the stock or on the stock-carrying plate, so that theoperation of said mechanism will not be affected by the vibration orjarring of the machine.
